Rev. Peebles Fleming
Minister of Highbury Quadrant Congregational Church in 1957.
Our photo comes from Jersey Heritage where it is captioned: "Photograph of the Reverend W. Peebles Fleming, the new minister of St John's Congregational Church" and handwritten, below the photo, "14 Nov. 1950".
We also found Rev.W. Peebles Fleming officiating at a funeral in Whitstable, Sussex in 1940.
Seems likely that these are both our man.
